The numbers of ?(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be (107:0±0:8) ×106 and (341:1±2:1)×106 , respectively, by counting inclusive hadronic events, where the uncertainties are systematic and the statistical uncertainties are negligible. The number of events for the sample taken in 2009 is consistent with that of the previous measurement. The total number of ?(3686) events for the two data taking periods is (448:1±2:9)×106 . © Article funded by SCOAP3 and published under licence by Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd., DPT2006K-120470, 11205082 CRC 1044 11235011, 11425524, 11335008, 11322544, 11475207 530-4CDP03 DE-FG02-05ER41374, DE-SC-0010118, DE-SC-0010504 2009CB825200 GSI: GSI SCOAP3 KJCX2-YW-N29, U1532258, KJCX2-YW-N45, 11179007, U1232201, U1532257, 11079008, 11179014 NRF: R32-2008-000-10155-0, Received 13 September 2017, Revised 2 December 2017, Published online 5 January 2018 ?
